The “Maritime Autonomous Navigation using Alternative Absolute positioning techniques” (MANAA) project will provide new ways of integrating millennia old celestial navigation techniques with state-of-the-art technology and thinking, whilst developing visual and non-visual spectrum optical techniques and sensors with the potential to observe celestial bodies independently of the lighting and…

The traditional mathematical approach to deriving Position Navigation and Timing (PNT) data from Global Navigation Satellite Systems (GNSS) does make some assumptions about the data being received. Machine Learning (ML) techniques could be used to instead of these traditional techniques to integrate GNSS signals and Signals of Opportunity (SOOP) signals in a way that doesn’t make these…

The objective of this activity is to design a prototype deployable satellite navigation antenna in Ka band. A review into possible use cases for such an antenna on a small sat platform, to be used for navigation functions in combination with mega constellations shall be performed. A trade-off between different design solutions shall be performed, such as deployable helical or reflectors, and the…

The objective of the project is to focus on and implement existing time transfer data protocols (NTP, NTS...) and the feasibility of their integration in existing constellations. The scope is to study the overlay of data time transfer protocols (“Data TT”) onto satellite communication protocols. However, the perspective to study 5G NTN frames (“5G TT”) is not left out. The proposed…

The NUMEROSO activity aims to assess the benefits of integrating Signals of Opportunity (SOOPs) with GNSS signals for navigation purposes, considering both terrestrial (such as 5G mobile or WiFi) and space-based (such as those transmitted by LEO satellites, or non-terrestrial networks) SOOPs. Leveraging advanced machine learning (ML) techniques, NUMEROSO will make use of SOOPs to enhance…

Optical atomic clocks offer the potential for a new era of timekeeping, with laboratory systems at the world’s leading NMIs already demonstrating 100x improvements in accuracy compared with the microwave fountain clocks that offer the best realisations of the SIsecond. Enhanced PNT systems with these next-generation clock technologies could facilitate GNSS constellations with significantly-…

In the LEO project the next generation of modulators integrated on a silicon nitride platform will be realized. We will use the technique of micro-transferprinting to integrate lithium niobate on top of silicon nitride waveguides. This back-end integration allows for being compatible with wafer scale processing in CMOS fabs. The modulators are targeting bandwidths beyond 100 Ghz

First time development of an on-board autonomous digital beamforming of multiple beams for small/compact new space payloads, with medium/large number of channels supported. The innovation also relies on the number of channels, dynamic beamforming, low power. The activity will review the digital beamforming requirements for GNSS-R and Radio Occultation payloads, define a digital processor…

The objective of ACTOR (AuthentiCation Techniques for Optical time-transfeR) is to design, develop, manufacture and validate an authentication method for high-accuracy time transfer techniques over optical fibre, without a major loss of accuracy. The system is composed of a master and a slave demonstrator unit, each including software (SW)/protocol allowing authentication and integrity protection…
